[0029] Working principle: When the construction personnel place the Bailey frame on the clamping plates a111 on both sides, the motor 102 is started, and the motor 102 drives the first gear 103 to rotate. The first gear 103 is meshed with the second gear 104, driving the second gear 104 to rotate. The first threaded rod 105 rotates with the second gear 104, and the movable sleeve 106 drives the clamping plates a111 on both sides to rise through the support frame 107, driving the clamping plate b113 to rise. When the upper clamping plate b113 rises to the top of the sliding column 203 and stops moving, the lower clamping plate a111 also stops running, so that The clamping plate a111 cooperates with the clamping plate b113 to clamp and fix the Bailey frame to prevent the Bailey frame from shaking when it rises. At the same time, the wheel 108 rises with the moving sleeve 106 through the support frame 107, so that the wheel 108 rises and does not contact the ground, preventing the wheel 108 from moving during the rising process of the device, causing the entire device to tilt.

At the place where there is no thread on the upper end, the first movable sleeve 106 no longer moves upward, and at the same time, the first protrusion 112 is driven upward to the movable block 208 by the first movable sleeve 106, so that the movable block 208 slides on the second groove, and the second protrusion 209 is inserted into the third groove on one side of the second threaded rod 204, so that the second threaded rod 204 rotates with the first threaded rod 105, so that the fixed plate 201 moves on the second threaded rod 204, thereby driving the four sets of telescopic rods 205 to rise, thereby driving the entire device to rise, so that the Bailey frame is raised to reach the required construction position. When the four telescopic rods 205 rise, the first rack 301 is driven to rise, and the first rack 301 drives the third gear 302 to rotate, so that the third gear 302 drives the second rack 303 to move downward, and the fixed cone 304 follows the second rack 303 to move downward and is inserted into the ground for fixation. At the same time, the third gear 302 drives the pointer 307 to rotate on the protection frame 306 through the rotating rod 305, so that the pointer 307 rotates to align with the measured value of the protection frame 306 when rotating, so that the construction personnel can clearly see the descending distance of the fixed cone 304.
